This is a cool idea. I am currently searching the web for Australian Falcon parts suppliers that would ship internationally. I want some Super Roo decals...and maybe some of those wicked Bathurst Globe wheels ($$$) that I see on the Australian Falcons. I just joined an Australian Falcon forum, I'll ask around there and get back to you. Hopefully I'll get a warm welcome from our Falcon friends down under.
Edit: I didn't realize this thread was so old. Either way, I am still interested in finding a source for Australian parts for my Falcon build. If anyone has any leads, let me know.
I just contacted these folks, and they are willing to ship internationally. They have a nice selection of parts.
